MACHINE VFOI- BARBING FENCE-WIRE.

SPECIFICATION formingpart of Letters Patent No. 253,675, dated February14, 1882.

Application filed February 19, 1878.

To all whom it may concern Be it known that I, JACOB BEo'rHEaToN, of

Ames, in the countyof Story and State of Iowa,

have invented certain new and useful Improve- 5 ments in a Machine forBarbing Fence-Wire,

of which the following is a description.

My invention has for its object the rapid. and secure fastening ot'barbs upon fence-wires by means of mechanism which holds the two [ofence-wires apart, admitting the ends ot the barb or barbs between them,and a device which windsa portion of the barb or barbs around thefence-wires.

It consists in a fixed holder having two or more apertures for thepassage of the main wires, in combination with a revolving and areciprocating coilin g-cylinder havi n g barb-coiling lugs and mountedou the holder so as to be free to revolve and reciprocate withoutiinzoparting its motion thereto; also, in the combination, with means forsupporting two or more mainfence-wires adapted to permit their passageand at the same time prevent them from twisting, of mechanismfor-catching one end 2 5 of the barbinserted between the aforesaid mainwires and twisting the said end spirally around both or all the mainwires; also, the non-rotating holder, adapted to prevent twisting of themain fence-wires, thebarb-winder, and the 3o spring, combined andarranged as will be eX- plained, so that. the barb-windet' surroundssaid holder and is adapted to move endwise during the coiling operationagainst the pressure of the spring without imparting its end- 3 5 wiseor rotary movement to said holder, all as will now be more fully setforth hereinafter. During the' barbing operation the cylinder has also amovement lengthwise of the fence-wires in order to coil the barb orbarbs spirally 4o around said wires. In order to the more perfeetoperation of the machine, a spring is combined with the coilingcylinder,so that the cylinder in coiling the .barb moves backward against thepressure of the spring and the springautomatically returns the saidcylinder into position for supplying a new barb. The fixed holder abovereferred to is not connected with the coiling-cylinder, and is notdesigned to receive motion therefrom; but it furnishes an' internalbearing, on which the cylinder is free to revolve and to move endwise.

In the accompanying drawings, Figure 1 is a perspective view of themachine with a portion of the barbing-cylinder broken away. Fig. 2 is adetail in perspective, showing the device as it begins the coiling. Asingle barbwire is here represented. Fig. 3 is a detail in `perspectiveas the coiling is just finished. A

four-point barb formed of two barb-wires-is here represented. Fig. 4 isa perspective view of the holder.

The hollow cylinder B can be revolved freely in the standards C, or inany suitable support, by handle D or by other means. It is also somounted on these supports that it may have a reciprocating movement inthe direction of its length. This cylinder is provided at its outer endwith the winding or bending lugs a. side ofathe cylinder B is placed theholder A, which is held so that it cannot revolve by means of a bail, d,extending back and through the slotted arm b, attached to the standard Dor otherwise made stationary. Y

The main body of the holder is a plain cylinder, (see Fig. 4,) and titsloosely within the coiling-cylinder B, which is therefore free torevolve and to move endwise thereon without imparting its rotary oreudwise motion to said holder.

In operating this device the two main fencewires c c are passed throughthe openings in the holder A, by which means, also, they are kept apartduring the barbin g process. Thus the barb wire or wires e e can bereadily passed between the main fence-wires, and said fence-wires areprevented from twisting upon each other.

I n operating this device to make a two-pron g barb the barb-wire e e isplaced diagonally across the face of the holder A and between the twomain wires c c, and then by turning the cylinderB one of the lugs a willcatch upon one end, e, of this wire c e' and twist it spirally about oraround the said main wires c c. During this operation the cylinder B ismoved endwise against the pressurel of a spring,

In-A

d', and thus this said peculiar twist is made in the barb. rIhis springis secured at one end upon the cylinder at h and at the other end on thestandard C. The wires c c are then moved forward and the cylinder Bthrown forward by the spring d. This spring may be a compressed spiral,as now shown, and will extend when the pressure is released and throwthe cylinder forward in position to form a new barb; but I may use anysuitable construction to accomplish the same end. When the barbed wirehas been fed a sufficient distance along the above barbin g process isrepeated.

When it is desired to apply two pieces of the barbing-wire for thepurpose of making a fourpoint barb, the two pieces of barbing-wire areplaced diagonally between the main wires and across the face of theholder, but each from an opposite side, so as to cross each other, andso that the lugs a will engage on the free end e ot" each barb-wire andwind both these wires about the main wires c c in the same manner as hasbeen above set ont.

Having now fully described my said invention and the manner of carryingthe same into effect, I would observe, in conclusion, that I do notclaim a non-rotating die or holder which isadapted by two or moreapertures or otherwise to prevent the main wires from twisting, and alsoat the same time to permit their passage through it, in combination withabarb- Windersurrounding` such guide and holder and receiving a rotarymovement. Nor do I claim broadly a non-rotating holder adapted toprevent the fence-wires from twisting and a rotating barb-Windersurrounding said holder when the barb-Winder and holder are both reciprocated longitudinally; but

What I do claim, and desire to secure by Letters Patent, is

1. A fixed holder having two or more apertures for the passage of themain wires, in combination with a revolving and a reciprocatingcoiling-cylinder having barb-ceiling lugs and mounted on the holder soas to be free to revolve and reciprocate without impartingits motionthereto, substantially as and for the purposes set forth. l

2. The combination, with means for supporting two or more mainfence-wires adapted to permit their passage and at the same time preventthem from twisting, ot' mechanism for catching one `end of the barbinserted between the aforesaid main wires and twisting the said endspirally around both or all the main wires, substantially as described.

3. The non-rotating holder adapted to prevent twisting ot the mainfence-wires, the barb-Winder, and the spring, combined and arranged asexplained, so that the barb-Winder surrounds said holder and is adaptedto move endwise during the coiling operation against the pressure of thespring without imparting its endwise or rotary motion to 4said holder,substantially as described.
